Weather Stripping
Wooden window sashes can add an elegant appearance to your home. They are also sturdy and will last for many years when they are maintained properly. However, they may become damaged or degrade in time due to exposure to elements and wear and tear. Fortunately, sash repair specialists can bring your windows back to their original condition and keep them looking fantastic for much longer than newer replacement windows.
The first step in sash window repairs is addressing weather stripping, which can be found on both the sash as well as the frame. If it's loose or worn out, it can lead to drafts, as well as other issues. Start by identifying the brand of Window Repair and the date of manufacture for the glass (etched on the glass's corner or on the aluminum spacers between panes). Then, remove the sash and mark its height and width to find replacement weather stripping to match.
Then, take it off and place it on a surface so that you can reach all four sides. If your sash was double-hung, take out the weights using their ropes that should have fallen into the pocket inside the jamb lining. After removing the sash with the utility knife, remove the weather stripping from the old sash by hand or using a putty blade.
When the sash is clean it is time to replace the parting stops. These are long pieces of wood that separate the two sashes. Pam prefers to replace them with standard 1/2-inch by 3/4-inch window trim from the lumberyard, however you can also use a piece of scrap wood.
After removing the stopper for the parting and cutting it to length after which, apply a thin layer of glazing compound to the bottom of the sash. Smooth the compound with your putty knife and let it dry for a minimum of a day. When the putty is fully dried, you can apply a topcoat of acrylic latex. This will help protect the putty, and give your sash an updated appearance.
Sash Hardware
The hardware that holds the window sashes can wear out over time and Window Repair use. This can result in the window or door repair that is difficult to open or close. The good news is that fixing and replacing this hardware is usually very simple and cost-effective. If you are having trouble opening a sash spray some grease into the jamb channel. Then slide the sash out to see if this resolves the issue. If the problem persists, it is most likely that the sash balance is off. You will need to take off the window sash in order to reach this hardware.
Sashes for windows should be able to open and close with little effort. However, this may be a challenge if the weights have been worn out or the sash-to rail meeting rail is not properly covered with. This issue could be caused by a variety of factors, including an absence of maintenance or an unmatched weight rating.
If the hinge arms of a window are starting to slide, this could cause the sash to slide and eventually strike the frame in the corner directly opposite the hinge arm (Photo 1). To address this issue, first make sure the sash fits squarely in the frame's opening and then remove it from the window. If the sash is secured to the hinge arm, you'll have to remove the hinge arm and replace it (Photo 2). Then, put in the new sash (Photo 3).
Old windows, particularly those in older houses, can be difficult to open and close, because of sagging hinges and an overall lack of energy efficiency. In many cases just a few easy fixes can make these windows operate smoothly and save homeowners money on energy bills.
In order to make these repairs to the sash it is essential to have all the necessary tools in place before you begin. Start by marking the location of the hinge channel on the frame with pencil (Photo 1). This will make it easier to place the channel in the proper place when you are finished. Take the sash off and take out all the hardware, including the beads for parting, cords, and chains that help to hold the sash. The nozzle shield of the heat gun and medium setting will soften any putty that has been hardened. Remove the old sash, and put it in a bag that is labeled.
Sash Weights
Sash weights are able to be replaced to improve the operation of your window sash and decrease the energy cost. Sash weights are made of heavy iron or lead cylinders that are encased in a concealed cavity and connected by ropes to the moveable window sash. They are counterbalancers which allows the window to be opened and closed without the need for mechanical or electrical devices. When they fail, sashweights are usually left unnoticed or disabled by homeowners.
A sash weight that has fallen out of the cavity is difficult to get back It is therefore important to find a replacement that fits properly. You will also require a fresh piece of string, a length of sashcord and a few sashpulleys for tying the weights you are replacing to the cord.
Mortise and Tenon joints are used to join old wood windows. Hammers and pins can be used to take out the wood pegs that hold the components together. Most of these pegs have an enormous diameter on one side and a smaller one on the other side, so it is crucial to take out the smaller-diameter sides first. Later sashes utilized glue instead of pins. They can be separated by using a knife or a mallet.
After the sash is removed, you can take off the stops on the sash and get access to the weight pockets. This is typically done by drilling an opening at the bottom of every jamb. This hole is covered by an access panel of wood that can be ripped off to let you see the inner workings of the frame.
Once you have the sash stopped and the access panel removed, you will be able to remove the weight from the sash and replace it with the new. Make sure you weigh the sash before you begin, as the old weights may be different in size from what you require. Once the new weight is installed, thread an appropriate length of string through the pulling mechanism. Then nail the string to the frame, but leave a few inches of string sticking out from the head for future adjustment.
Sash Cords
In the majority of old double-hung windows, a cord or chain is connected to the weights. This keeps the sashes of the jamb in a balanced manner. Over time, these cords may become damaged and make it impossible to raise windows. A new sash cable will restore the ability to move and lower the sash and keep it in position when opened.
The first step to replace sash cords is to locate and remove the access panels within the jambs. They are usually screwed or nailed in and must be removed. You may be able to use a hammer and chisel to remove them however, it is always best to lay down dust sheets prior to starting any work.
After you have removed the access panel, you are able to begin to work on the sash. Make the small parting beads (also known as "tie rails") out of their grooves using flat bar or chisel. It is important to take your time because they are usually wedged or nailed in place. If the sash remains in place, pry the mortise and tenon joints free with a hammer or screwdriver and then remove each wood peg. The sash should move freely now, but it might require some lubrication to make it feel less stiff.
With the sash in an open position, measure enough sash cord/chain to extend from the pulley at the top of the jamb to the sash slot on the bottom. Cut the cord or chain and attach it in Step 6 above. You can employ a hammer and screws or nails, however nails are less likely to cause damage.
It is best to keep the original weights if you've purchased a kit that will replace the counterbalance. They're not expensive and are easy to install if purchased them at architectural salvage stores. Based on the dimensions and shape of your window you might need to install one or two sashweights to keep it open.
